Hmm Fastidious, not found in dictionary. Capricious: 1. subject to, led by, or indicative of caprice or whim; erratic.
Other than the human norm, I don't think I'm capricious. I'm someone who fell in love with single coil pickups first, humbuckers second, yet loves them all for what they are, or at least that's what I try to be. I'm not trying to nail vintage strat voicing. I have a Lite Ash strat, and 3x A2Ps goodness through a Twin Reverb is hard to beat, but I like how it sounds, not how it sounds like someone else. In fact, I can't think of who else it sounds like, really. The guitar came stock with SD single coils, so I like it because I didn't have to mod it. I like my Showmaster for that reason. As for quack, it had to be explained to me, but I knew what it was. Twang I already knew, but reading about surf music helped me more fully understand it.
Bottom line to me is that a guitar comes stock with SD pickups, so I don't lose money on modding it. I love the clarity of Duncans, and the versatility they give, whether Strat or humbucker. I'll eventually own one with filtertrons, and one with P-90's (probably semi-hollow). I want to own one of each, and learn to be versatile with them all as a player. That's me.
"You're unique ... just like everyone else."
And for what it's worth, no pickup is better than another: they're all equal, just "gifted" in different ways, if you catch my drift. I can't play Metallica with a vintage neck single coil in the neck any more than I can play surf with an Invader.

Different roles, but no pickup can do everything
